## What is the formula for finding the area of a pentagon?

Using a Formula. Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don’t know the perimeter, calculate it from the side length: p = 5s, where s is the side length.

## How do you find the area of a regular polygon Square?

A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles). To find the area of a regular polygon, you use an apothem — a segment that joins the polygon’s center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).

## How do you find the area of a multi sided shape?

## What is the formula to find area of quadrilateral?

For squares, multiply one side by itself to get the area. If you have a parallelogram, multiply the diagonals and divide by 2 to get the area. To find the area of a trapezoid, add the base and the height together, and divide that number by 2 times the height.
